In the games

Brock's title is "The Rock-Solid Pokémon Trainer." Brock is quite proud of his rock-hard willpower, and uses Rock-type Pokémon to complement this.

Brock is one of the few truly serious professional Pokémon Trainers in the Pewter City area. He's tough, people respect him, and most admire him. Supposedly, it's hard to get him to laugh or drop his serious demeanor, but when he does, he can't stop.

In HeartGold and SoulSilver Versions, after he is defeated and all 16 badges have been obtained, he can be found in Diglett's Cave near Pewter City on any day between noon and 3 PM, and he will offer his Pokégear number if he is spoken to there. If he is called on Saturday nights, he will be up for a rematch at the Fighting Dojo. After his Pokégear number has been obtained, he will reappear in Diglett's Cave every day between 5 PM and 8 PM, and the player can have a photograph taken with him there. If he is spoken to in Diglett's Cave on a Saturday, he will offer to trade a Rhyhorn that knows Thunder Fang for a Bonsly.

"There are all kinds of Trainers in the world! Some raise Pokémon for fights. Some see them as pets. I'm in training to become a Pokémon Breeder. If you take your Pokémon training seriously, go visit the gym in Cerulean and test your abilities!"

"Wow, it's not often that we get a challenger from Johto. I'm Brock, the Pewter Gym Leader. I'm an expert on Rock-type Pokémon. My Pokémon are impervious to most physical attacks. You'll have a hard time inflicting any damage. Come on!"

"I took you for granted, and so I lost. As proof of your victory, I confer on you this...the official Pokémon League Boulder Badge."

Pokégear Phone

Calling the player:

"This is Brock. Oh hey, how are you doing? There are so many different types of Pokémon in the world. As you could guess, I like Rock-type Pokémon best. They're solid and rough, and yet somewhat brittle at the same time. Once you've really gotten to know them, they're quite cute. What do you think?"

Calling him:

"Hello... What's up? I'm doing great! I can take a break on Saturday evenings, if you want to give me a call again then."

On Saturdays:

"Hello... What's up? I'm doing great! Hey, you called at just the right time! I'm free right now. Want to battle me again?"

No: "Is that so... Well, I suppose you must have a lot of things to do yourself..."

Yes: "All right, all right! I'm looking forward to it! I'll meet you at the Fighting Dojo in Saffron City! I won't be at the Pewter Gym, all right? Don't get confused!"

In the anime

In the anime, like later Gym Leaders, Brock appeared primarily as an opponent to Ash in his debut episode; unlike later Gym Leaders, he requested to join Ash on his journey, aiming to be the world's greatest Pokémon Breeder. In doing so, Brock left the Gym in the hands of his father, Flint, who had finally revealed himself to have returned from his journey. Brock advised Ash throughout the Kanto series, then left briefly during the Orange Archipelago arc to assist Professor Ivy. He returned to Ash's side in Johto, and with brief returns to Pewter City at the end of each series, joined him for his journeys in Hoenn and Sinnoh as well; however, he now wants to become a Pokémon Doctor.

Brock mainly provides an advisory role to the other main characters of the anime, being several years older than the rest of them. His knowledge of Pokémon battles is great, causing him to often referee matches between Ash and others. Brock also fancies himself as something of a ladies' man, though each time he hits on someone he is either rejected outright, pulled away by Misty or Max, or, most recently, Poison Jabbed by his Croagunk.

In the Magical Pokémon Journey manga

Ash and Brock in Magical Pokémon Journey

Brock, along with Ash and Misty, make cameo appearances in bonus chapters of the Magical Pokémon Journey manga. In the bonus chapters, Brock and co. have mistakenly wandered into the world Magical Pokémon Journey is set in. The bonus chapters chronicle their attempts to return to their own world (of the anime) and their encounters with various aspects of the Magical Pokémon Journey canon which differ from the anime's canon (such as the use of Poké Balls).

In the movie manga adaptations

Brock with his friends

As Brock has appeared in every movie prior to Best Wishes, he has appeared in every manga adaptation of it. His team in the manga adaptations are the same as in the films.

In the Pokémon Adventures manga

Brock debuts in Onix is On! of the Red, Green & Blue chapter, however he is mentioned earlier by Blue in Wanted: Pikachu! about being bored by no-one being able to defeat him, or even get past the preliminaries. To gain access to Brock, a Trainer must win several rounds of battles against special Trainers of the Gym, and all of those battles are watched by him from a special room.

Brock is a brave Trainer, and he assists Erika and Misty in their battles against Team Rocket. He also gave Yellow a Graveler after the good Gym Leaders of Kanto battled Agatha's mind-controlling Gastly. However, he is also shown to be quick to anger and restless in his search for a good battle, and when discovering that Red's Pika, the only remaining Pokémon of his, was disobedient, deemed his wins "dumb luck" and sought for a finisher attack instantly. However, when the boy begins to gain his Pokémon's trust, it chooses to fight for him and defeats his Onix.

After Blaine figured out that Red must have been at Mt. Moon before going missing, Brock volunteered to search there, since Mt. Moon was closest to Pewter City. He then found a cast of Red frozen in ice there and contacted Blaine. Before all of the information could be exchanged, he found out that Pewter City was under attack by a group of Bruno's Machop that was searching for Brock's Boulder Badge, and he left to protect it.

A few years later, he, along with Erika and Misty, traveled to Johto for the Gym Leader Tournament at the Indigo Plateau, where he faced off against the expert of the newly discovered Steel-type, Jasmine. He lost the match and later fought against Team Rocket on the Magnet Train.

Pokémon

On hand

Brock owns six Geodude, nicknamed Geoone, Geotwo and Geothree and so on. The often grasp each others wrists in order to circle around Brock in order to protect him. During the Gold, Silver & Crystal chapter, they used their Magnitude to stop the Magnet Train. However, the impact sent it off course, causing it to almost crash before it was saved by Red's Snorlax.

Onix is arguably Brock's most powerful Pokémon and is apparently well known for its speed, which causes shock waves when it moves. Onix was first used in battle against Red's Pika. Despite the type advantage, Onix was defeated by the small electric type after it came to fight for Red of its own will. Three years later, Onix was sent out by Brock to use as a bridge when a bridge in the Tohjo Falls went out while Brock, Erika and Misty were heading to Johto, during which Misty is joined by Suicune. However, it itself collapsed when they were all attacked by a large group of Zubat, Golbat and Crobat. Once the group finally made it to the Indigo Plateau, Brock used Onix in his battle with Jasmine. It lost to Jasmine's Steelix, which he initially mistook as an Onix of a different variety due to its rock covering used to hide the fact that it was a new, undiscovered species at the time.

Brock met Kabutops when it was a Kabuto in the Pewter Museum of Science during the Elite Four's invasion of Kanto, and received and later evolved it for protecting it during the ordeal. It knows many ancient attacks and is a very powerful member of Brock's team and was able to easily hold its own against Jasmine's Amphy, nearly winning him the match.
